A number of 5-nitro-N,N-diphenylhydrazinopyrimidines were synthesized.Free radicals were obtained by oxidation of these compounds with PbO2.The stabilities of 5-nitro-4-pyrimidinylhydrazyl radicals are close to the stability of the α,α-diphenyl-β-2,4-dinitrophenylhydrazyl radical.The structures of the compounds obtained were confirmed by the UV, IR, PMR, and EPR spectra.
